Problems solved by technology

[0002] At this stage, the hemostasis of each hospital for dialysis is cotton. Because dialysis patients have used anticoagulants for a long time, their coagulation effect is worse than that of normal people. The hemostatic bandage, the blood vessel will be deformed and produce some other lesions if it is compressed for a long time

Embodiment 1

[0035] The invention provides a technical solution: a dialysis hemostatic dressing, the preparation process comprises the following steps:

[0036] Step S1: take 2% chitosan and purified water and place them in a stirring tank, and then premix at a rotating speed of 30r / min to form a suspension until there is no agglomeration in the solution;

[0037] Step S2: add 1% glacial acetic acid to the stirred tank of step S1, then mix at a rotating speed of 50r / min, and the mixing time is 10 hours. After the mixing is completed, the solution is a colorless or yellow viscous liquid, and the viscosity is required to be 15mPA.s;

[0038] Step S3: filter the solution obtained in step S2 through a 200-mesh filter screen;

[0039] Step S4: pour the solution obtained in step S3 into the freeze-drying tray, and let it stand for defoaming for 12 hours;

[0040] Step S5: put the freeze-drying tray obtained in step S4 into the freeze-drying machine, the temperature of the freeze-drying machine ...

Abstract

The invention provides a dialysis haemostatic dressing and a preparation process thereof, the dialysis haemostatic dressing comprises chitosan, glacial acetic acid and purified water, the mass percentage of the chitosan in the dressing is 2%-5%, the mass percentage of the glacial acetic acid in the dressing is 1%-4%, and the balance is purified water according to the total mass of the dialysis haemostatic dressing being 100%. When the hemostasis bandage is used, the use time of the hemostasis bandage is greatly shortened, so that the blood vessel compression time is shortened, the service life of autologous internal arteriovenous fistula of a patient can be prolonged to a certain extent, and a series of blood vessel problem lesions such as pseudoaneurysm are reduced.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a dialysis hemostatic dressing and a preparation process thereof. Background technique [0002] At this stage, the dialysis hemostasis in hospitals is cotton hemostasis. Because dialysis patients use anticoagulants for a long time, their self-coagulation effect is worse than that of normal people. Therefore, the use of cotton hemostasis takes a long time and there is a risk that the bleeding cannot be stopped. In addition, many patients use it for a long time. Hemostatic bandages, long-term compression of blood vessels will deform and produce some other lesions. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to propose a dialysis hemostatic dressing and a preparation process for the deficiencies in the above-mentioned prior art. [0004] The technical scheme adopted by the present invention to solve its technical probl...
